1992 Lexus LS 400 acceleration problem

1992 Lexus LS400 - runs fine to about 40 mph - acts like starving for fuel - push accelerator more and picks up about 55-60 mph and runs fine - bad TPS? ECU issue?

Try unplugging the mass airflow connection and check then. If not, probably the ECM. I had same problem.
